I am trunking a Cisco 3750 to an Extreme 450 and when I plug into the port I'm unable to pull an address from the DHCP server on the extreme side.

Below is the 3750 config;

interface Port-channel7
 description Etherchannel Trunks to Extreme Switch
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 998
 switchport trunk allowed vlan 998,999
 switchport mode trunk
end
!
interface GigabitEthernet1/0/21
 description temp connection to extreme core
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 998
 switchport trunk allowed vlan 998,999
 switchport mode trunk
 channel-group 7 mode active
end
!
interface GigabitEthernet1/0/23
 description temp connection to extreme core
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 998
 switchport trunk allowed vlan 998,999
 switchport mode trunk
 channel-group 7 mode active
end
!
interface GigabitEthernet2/0/15
 description temp connx to Vlan 998
 switchport access vlan 998

Is the extreme switch using LACP also and the same native vlan?

Which vlan are you trying to receive dchp from.

From a 10.x.x.x but does the config look to be good for the most part

Would need to see the config on both ends as well as the any dhcp relay configs if required but yes the port channel config on the Cisco side looks good.

I am assuming this is the port channel and trunk config config:

enable sharing 21 grouping 21-22 algorithm address-based L2 lacp
configure vlan ip11 add ports 1-2 tagged
configure vlan ip11 add ports 17 untagged
configure vlan ip191 add ports 2 tagged
configure vlan ip923 add ports 2 tagged
configure vlan ip998 add ports 1-2, 21 tagged
configure vlan ip998 add ports 3-15, 18-20, 23-48 untagged
configure vlan ip999 add ports 1-2, 21 tagged
configure vlan ip999 add ports 16 untagged
configure vlan Mgmt ipaddress 172.16.xx.xxx 255.255.255.224

#

If so I don't see any config issues. I also assume this switch is layer 2 only correct?

That is correct those are the trunked port channel config and it is a layer 2 switch. I was thinking I had to put a dhcp relay on the cisco side but there is no bootprelay on the extreme side.

You will have to put a dchp relay on the cisco side if you are trying to get dhcp addresses from a vlan other than the one that the dhcp server is sitting on. Which network is the dhcp server on and which network is dhcp failing?

The dhcp server is sitting on a 10.2.101.x network which means that I'd have to configure the vlan interface with IP on my cisco side correct ?

sample below:

interface Vlan998
 ip address 192.168.998.1 255.255.255.0
 ip helper-address 10.2.101.xx
